Seismic Refraction investigations are commonly used to determine
bedrock depth & rippability.
Seismic Reflection surveys are
used to map, detect, & delineate geologic conditions including the
bedrock surface, voids, water table and layer geometry (folds).
The Seismic Refraction & Reflection (SRR) system is
designed to allow for either seismic refraction or seismic reflection
data acquisition. The SRR system, which is designed for shallow
surveys, can also be used for detecting voids in large civil structures
such as dams (seismic reflection).
Seismic Refraction surveys are used for excavation
purposes to map the bedrock depth and evaluation rock rippability.
Seismic refraction measurements are applicable in mapping subsurface
conditions for various uses including geologic, geotechnical,
hydrologic, environmental, mineral exploration, petroleum exploration,
and archaeological investigations. Seismic Refraction
investigations are commonly used to determine layer thickness and/or
the subsurface compressional wave velocity of the
overburden and underlying bedrock or to water table, stratigraphy,
lithology, structure, and fractures. This inherently shallow
technique requires that compressional seismic wave velocities increase
with depth so wave refraction occurs.
Seismic Reflection surveys are used to map, detect, and delineate
geologic conditions including the bedrock surface, confining layers
(aquitards), faults, lithologic stratigraphy, voids, water table,
fracture systems, and layer geometry (folds). This methodology requires
that the target be sufficiently deep, so that the incoming reflected
wave arrives after the surface wave generated from the impact. Near-surface
seismic-reflection data are generally high-resolution (dominant
frequency above 80 Hz) and image depths from around 20 ft (6 m)
to as much as several hundred feet (100+ meters).
Training
Hands-on training is available for all of our Nondestructive Testing
Methods at our Wheat Ridge, Colorado (USA) location, which is a
suburb located appromately 15 minutes northwest of downtown Denver. Training
may be available at your location by one of our agents upon special arrangement.
